| Title | Agreement State Report - Malfunctioning Shutter on Density Gauge |
| Event Description | The following information was provided by the State of Arkansas via email:
During routine shutter checks performed by the licensee on September 9, 2016, the licensee noted higher than normal readings when closing the shutter on a Ohmart Model SH-100 BS, weight gauge. The gauge contains 50 milliCuries of Cesium-137. The gauge is in a secure storage area and radiation exposure is maintained at less than 2 mR/hr. The licensee has contacted the supplier and requested disposal as the gauge in question was in storage and not being used. In accordance with RH-1502.f.2 (10 CFR 30.50(b)(2)) the malfunctioning shutter is reportable within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The State of Arkansas is awaiting a written report from the licensee and final disposition information for the gauge. The State's event number is AR-2016-010. The Licensee notified the State of Arkansas of the event on September 9, 2016, at 1430 CDT.
The following information was received via E-mail: Upon examination by the licensee's RSO it was determined that the shielding material for the gauge had been slid past the detent or retaining pins until it was removed for the source holder. This is part of the design of these gauges. The RSO returned the shielding material to the normal operating position, engaging the retaining pins and the gauge is now shielded. The shutter is working as designed. The Department considers this event to be closed. Notified R4DO (KOZAL) and NMSS EVENTS NOTIFICATION. |
